APPARATUS FOR TREATING INGANDTESCENT MANTLES.

Application filed July 6, 1914, Serial No. 849,045.

To all whom it may concern:

Be it known that I, JAcoB IeNo'r Rosin, a citizen of the United States, residing at town of Harrow, county of Middlesex, Eng land, have invented certain new and useful Improvements in Apparatus for Treating Incandescent Mantles, of which the following is a full, clear, and exact description.

My invention relates to an apparatus for treating incandescent mantles, by which I mean mantles used for incandescent burners of various kinds, and has for its object to provide a simple and eficient means for applying stiffening liquids to such mantles. It further has for its object to provide an apparatus which is automatic in its action and produces a uniform result.

The following is a description of my invention, reference being had to the accompanying drawings, in which Figure 1 shows, partly in front elevation and partly in section, a machine embodying my invention;

Fig. 2 shows a plan view of the machine, parts being broken away on the line 22, Fi 1.

Figs. 2 and 2 show an elevation and section of a modified distender mounted on the machine spindle;

Fig. 3 shows a transverse section of the same on the line 3-3, Fig. 1, looking toward the left;

Fig. 4 shows a transverse section of the machine on the line 4-4, Fig. 1, looking toward the left;

Fig. 5 shows a transverse section of parts of the machine on the line 55, Fig. 1, looking toward the right;

Fig. 6 shows a detail of gearing;

Fig. 7 shows a plan view of a holder forming part of the machine;

Fig. 8 shows a similar view of the holder with the parts in different position;

Fig. 9 shows a section of the holder on the line 99, Fig. 7

Referring more particularly to the drawing, 1 is the base of the machine having a frame consisting of uprights 2, a top plate 3, and bearings 4-4. Depending from the top plate are bearings 55 in which is mounted the main shaft 6. This main shaft is provided with a mutilated gear 7 and a complete gear 8, the latter of which engages with an intermediate gear 9, which in turn engages with the gear 10 on a shaft 11 carrying at each end a spindle 12 provided with Specification of Letters Patent.

a friction spring 13. The shaft 11 is also provided with adjustable collars 14.

Upon the spindles 12 are mounted holders consisting of a base plate 15 having recesses 16 and a tubular extension therefrom 17. This tubular extension is provided with a yielding end piece 18 which is held in eX- tended position by spring 19, its outward movement being limited by the pin 19. Surrounding the base of the holder is a ring 20 having recesses 21 and carrying a stop 22 which limits its movement of rotation about the base 15. The exterior of the base 15 and the interior of the ring 20 are provided with screw threads 23 which serve to hold the ring upon the base.

Mounted on the top plate is a movable plate 24 carrying two nozzles 25, the discharge openings of which are directed toward the holders. These nozzles as shown are atomizing nozzles and act to convert the stiffening fluid supplied thereto into a stream of finely divided liquid. 26 is a container for the stifiening liquid supported by a bracket 26. 27 is a pipe leading there from to a manifold 28 from which lead tubes 29 to chambers 30 of the nozzles. The passage of fluid from this chamber is controlled by a needle valve 31. The spring 32 bearing against a shoulder 33 normally tends to hold this needle valve closed. A lever 34 pivoted at 35 when moved to the position shown in dotted lines, Fig. 4, opens the needle valve permitting the liquid to discharge. The container 26 of liquid to be applied is above the nozzle, so that the liquid is fed to the nozzleby gravity, being applied to the mantle under pressure by compressed air preferably directed as shown. Surrounding the chamber 30 is a passage 36 which is connected by a pipe 37 to an air valve 38 which controls gas such as air led by the pipe 39 from any convenient source of compressed air or other gas. Mounted upon the shaft 6 is a cam 40 which acts upon a lever 41 which in turn acts upon the rod 42 of the air valve so that when the cam is in the position shown in Fig. 3, the air valve is closed while when in the position shown in dotted lines Fig. 3, the air valve is opened. Mounted upon the main shaft 6 are two other cams 43 which control the liquid supply by actuating the needle valves. These cams when in the position shown in Fig. 3, permit the liquid supply to be out off.

/Vhen turned from that position, they engage slides 44 which are provided withadjustable abutments 45. These abutments are normally clamped upon the slides in definite positions and when the slides 44 are charge openings of the nozzles. The cams.

40 and 43 are so shaped and. timed that the cam 40 opens the air valve before the cams 43 open the liquid valves. The cam 40 also maintainsthe air valve open until after the cams 43 have permitted the liquid valves to close.

The inner ends of the mantles 46 surround distenders 47, which in the form shown in Fig. 1, while permanently attached to the mantle perform the function of holding the lower ends of the mantles in shape to be treated, and coeperate with the other elements of the machine. These distenders are provided with three radial projections 48, which are useful in supporting the distender' and with it the mantle when in use in the burner, and. also serve to hold. the distender to the holder in the form shown. In mounting the mantle upon the holder these radial projections of the distender areinserted in the recesses 21 of. the ring 20 with the parts in the position shown in Fig. 7. The ring 20'is then turned to the position shown in Fig.8, thereby clamping the distender and mantle to the holder. As the radial projections 48are'being passed through the openings 21 of the ring 20, the movable end 18 of the holder is depressed against the action of the spring 19. When the distender 47 is secured in position and the upper end 18 of the holder is released, the spring 19 acts to force the end 18 outward and put the mantle under a slight tension and to extend it longitudinally, causing it to assume the shap shown in Fig. 1. 1

The plate 24 which carries the nozzles is movable forwardly and rearwardly upon the late 3 and can be held in adjusted position y the thumb screws 49. It is also provided at each end with an index 50 moving over a scale 51' to aid in adjusting the position of the plate 24.

Suspended from the top plate as shown in Fig. 5 is a worm 52 on the shaft of which is mounted a pulley 53 driven by a belt 54' from any convenient source of power. A loose pulley 55 is also mounted upon the shaft of the worm. The worm meshes with a worm wheel 56 which is connectedto a gear 57 in line with the mutilated gear 7 above referred to. The shaft 6 is provided with a crank or other manual devicev 58' so; that it together with the gear 7 can be givena slight turn sufficient to bring the teeth of the mutilated gear7 into engagement with the teeth of the gear 57.

Instead of the distender connected to the mantle a separate distender 47 such as shown in Figs. 2 and 2*, may be used. In such case the distender47 is placed upon the spindle, and the skirt of the mantle being placed thereon, treated with the fluid. Preferably these distenders 47 are made separablefrom the spindles so that the holders above described may be substituted therefor when desired.-

The operation ofthe apparatus is as follows. The nozzles are first adjusted at the proper distance fromthe'mantle by moving the plate 24 and securing it in proper position. This affects the relationof the lever S4 to the slide 44 and the movable abutments 45 may have tobe-adjusted so as to make the cams 43 open the needle valves 31 to the The handle 58 is then given" causes the gear 8 to revolve the spindles carrying the mantles, whereupon the cam 40 opens the air valve after which the cams 43' open the needle valves, whereupon streams of stiffening fluid under pressure are pro-- duceddirected toward the mantle. The action continues until, with the gearing shown, the mantle has revolved twice, whereupon the cams 43 permit needle valves to close and shut oh the liquid, after which the cam 40'permits the air valve to close-and out off the air. At a later period the mutilated part of the gear 7 reaches the gear 56 with. the result that the holders together with the mantles stop r'otating and the machine, except for the idle action of the worm 52', is at rest. The holders are then removed and other holder's having mantles and-distenders 47' mounted thereon aresubstituted andafter another forward movement of the crank,5l8

the action is repeated. .Wheh the. distender 47 is used the holder is omitted.

From the foregoing it will be seen that in carrying out the process with the apparatus above referredto, a mantle is first distended and then rotated about its axis; During such rotation liquid under pressure is discharged and applied to the mantle; The liquid thus applied thoroughly im'pregnates the material of the mantle in a'narrowbelt and enables the obtainingof' a uniform and 7 perfect product.

If desired, the worm V V stopped by shifting the belt 54" from the fast pulley 53' to the loose pulley-55' bymeans of the belt' shifter 5'9.
